Hydropower Energy Facts

geothermal or hydroelectricity

Hydropower, often called hydraulic energy, is the application of fast-moving or falling water to generate electricity using pressure or momentum to create electricity. This is done by transferring the kinetic or gravitational potential energy of moving water to generate electricity. Hydropower is an effective and efficient means of green energy production. Hydropower plants can provide enough electricity to completely eliminate your electricity bill. However, you can also choose to combine hydropower with other forms of clean energy like solar energy, wind power, geothermal or hydroelectricity.

Hydroelectric power is an alternative form of energy source for electricity production that runs through rivers. There are basically two types of hydropower systems; electrical flow-wheel energy source (FWE) and electric-hydraulically powered turbine (EHT). Basically, there is an electric motor that is powered by turbines that spin in order to generate electricity. As the name implies, the electrical energy produced by the hydrazine is directly related to the amount of water flowing through the river. The greater the water flow, the higher the electricity produced.

hydropower systems

There are basically two types of hydropower systems; river turbines and run-of river turbines (RO) used in hydropower plants. The first type produces electricity by using large rotating blades on the upstream side of the river. The blades are usually made out of PVC pipes lined along the bottom of the riverbed. The turbine is connected to a controller that causes it to rotate using the movement of the river current.

The other type of hydropower system is run-of-river (RO). This is more energy efficient and has a lower impact on the environment compared to turbine generators. In a run-of river system, the electricity produced is directly proportional to the amount of moving water. If you compare the discharge of a tidal wave with that of a river, you will notice that a tidal wave is about four times stronger than the electric power produced by a single hydropower dam. In this way, RO hydropower systems have provided an alternative to hydropower generated through hydropower dams which contributes to climate change.

buildup of soil erosion

Hydropower has been able to generate electricity even in areas where hydroelectric power has previously been established. For instance, in parts of the US and Canada, hydroelectric power plants are able to generate electricity even during periods of drought. For some regions in the US, hydropower can even help to reduce agricultural dependence on fossil fuels. In addition, hydropower helps to keep the air clean because it generates smaller pollution particles and does not contribute to the buildup of soil erosion and sedimentation due to run-off from larger dams.

Hydropower has provided tremendous momentum for change. Even developing nations that lack abundant quantities of freshwater are now establishing themselves as major players in global energy markets by harnessing hydropower to provide electricity. Hydropower plants can even be built in remote areas where access to running water is impossible. Hydropower has also contributed to the decrease in greenhouse gas emissions which have been a contributing cause to climate change. Now, even countries with scant rainfall can generate electricity through hydropower if the proper tools and guidelines for construction are implemented.
